Description

Mobile commerce service device, mobile commerce service method using ultrasonic transceiving device and recording medium recording computer program

The present invention relates to a mobile commerce service device, a mobile commerce service method using an ultrasonic transmitting and receiving device, and a recording medium on which a computer program is recorded. The present invention relates to a mobile commerce service apparatus for providing a mobile commerce service, a mobile commerce service method using an ultrasonic transceiver device, and a recording medium on which a computer program is recorded.

As information and communication technology (ICT) technology is rapidly developed and utilized, the convergence of various services and systems is rapidly progressing. ICT technology through GPS (Global Positioning System) and Wi-Fi (Wireless Fidelity) has been applied in real life through the combination of performance improvement and location analysis technology. In particular, domestic and foreign companies provided location services for indoor spaces through IT technology.

Such technologies include GPS, Wireless Local Area Network (WLAN), Ultra WideBand (UWB), and Bluetooth technologies. Although GPS provides location information based on global coordinate system of wide area in outdoor environment, research on wide area indoor location recognition technology is actively conducted to compensate for this, since location information cannot be provided in indoor and urban dense areas.

Wi-Fi Positioning System (WPS) is a WLAN-based positioning technology that estimates the location of a terminal using Wi-Fi routers installed in various places. Because UWB uses impulses, bandwidth spreads and takes up a lot of bandwidth, which may cause problems in other wireless communication systems. However, the distance measurement of the position without obstacle interference between APs yields a relatively accurate distance, but the error range increases as the obstacles increase and the distance increases.

Recently used technology is BLE (Bluetooth Low Energy) based beacons. BLE Beacon is the biggest feature of the battery consumption of smart mobile devices compared to the existing Bluetooth protocol, it can automatically locate the user and provide related services even if the user does not take any action. The BLE beacon is the most attention-prone technology for positioning the IPS in the future, but it may be difficult to provide accurate location services as a single technology with the current technology.

Referring to FIG. 2, a primary location determination procedure is performed to determine the presence of a user located within a predetermined distance (in a mobile commerce service area) based on a POS or a sales stand in a store (step S200).

The ultrasonic transmitter and the ultrasonic receiver 100 may be implemented in a store. The ultrasound transmitter and the ultrasound receiver 100 may primarily perform a first location determination procedure for determining a location of a user in a store.

After synchronization, the position determination of the user device 140 may be performed based on the BLE module.

8 illustrates a method of identifying a user device by dividing a band of an ultrasound signal when the ultrasound transmitter / ultrasound receiver communicates with the user device based on the ultrasound signal.

Referring to FIG. 8, the ultrasound signal band 800 may be divided into a plurality of bands, and each of the divided ultrasound signal bands may be allocated as a radio resource for one user device 140. For example, when identification information of the user device 140 is obtained through the secondary position determination procedure, the ultrasound signal band uniquely allocated to the user device 140 based on the identification information of the user device 140 may be obtained. Ultrasound can be transmitted.

The ultrasonic transmitter may allocate the ultrasonic split signal band to the user device 140 after receiving the identification information from the user device 140. The ultrasound transmitter may determine the ultrasound signal band to be allocated to the user device 140 in consideration of the number of user devices 140 to communicate with and the allocation of the current ultrasound signal band.

After receiving the identification information of the user device 140, the ultrasound transmitter communicates with the user device 140 based on the ultrasonic split signal band allocated to the user device 140 by the user device 140, and the user device 140. ) Can be measured. The user device 140 may receive information on the allocated ultrasound divided signal band and transmit the duplicated ultrasound signal and the user device identification information through the allocated ultrasound divided signal band.

The ultrasonic transmitter / ultrasound receiver 100 may continuously track the position of the user device 140 based on the ultrasonic signal transmitted through the allocated ultrasonic split signal band.

The ultrasound transmitter / ultrasound receiver 100 may determine the number of user devices 140 located in the mobile commerce service area through a primary position determination procedure. The ultrasound transmitter / ultrasound receiver 100 may change the allocated ultrasound divided signal band based on the number of user devices 140.

For example, when the number of user devices 140 is less than x persons in the mobile commerce service area, the entire ultrasonic signal band 800 may be used to communicate with the user device 140 without any separate division. That is, if x or less, when different transmission periods are set to each other, since the collision does not occur much in the communication between the x user equipment 140 and the ultrasonic transmitter / ultrasonic receiver 100 separate ultrasonic waves The division of the signal band 800 may not be performed.

On the contrary, when the number of user devices 140 in the mobile commerce service area exceeds x, the division of the ultrasonic signal band 800 may be performed. For example, when the number of user devices 140 in the mobile commerce service area is x to y (where y> x), the ultrasonic signal band 800 is divided into two parts so that the first ultrasonic split signal band and the first ultrasonic split signal band 800 are divided. It can be divided into two ultrasonic split signal bands. In this case, one half of the user device 140 communicates with the ultrasonic transmitter / ultrasound receiver 100 via the first ultrasonic split signal band and the other half of the user device 140 uses the second ultrasonic split signal band. It can communicate with the ultrasonic transmitter / ultrasonic receiver 100 through.

Similarly, when the number of user devices 140 in the mobile commerce service area is y to z (where z> y), the ultrasonic signal band is divided into three parts so that the first ultrasonic split signal band and the second ultrasonic split signal band are divided. And a third ultrasonic splitting signal band. In this case, one third of the user device 140 communicates with the ultrasonic transmitter / ultrasound receiver 100 via the first ultrasonic split signal band and another third of the user device 140 uses the second ultrasonic split signal band. The third transmitter may communicate with the ultrasound transmitter / ultrasound receiver 100 and the other third of the user device 140 may communicate with the ultrasound transmitter / ultrasound receiver 100 through the third ultrasonic split signal band.

In this way, the possibility of collision that may occur in the ultrasonic signal-based communication may be reduced by dividing the ultrasonic signal band.

In the above case, the ultrasonic transmitter / ultrasound receiver 100 and the mobile commerce service providing apparatus 120 assign a virtual identifier for the user device 140 to identification information of the actual user device 140 for each band. Can be managed. Also, the ultrasound transmitter / ultrasound receiver 100 may determine an ultrasound signal band in which the user device 140 allocated for each virtual ID operates.

For example, if ten user devices (user devices 1 to 10) 140 exist in the mobile commerce service area, the ultrasonic transmitter / ultrasonic receiver 100 may be assigned to each of the user devices 1 to 5. Each of the virtual ID1 to the virtual ID5 may be allocated to the first ultrasound divided signal band. In addition, the ultrasound transmitter / ultrasound receiver 100 may allocate each of the virtual ID 6 to the virtual ID 10 to each of the user devices 6 to 10 and allocate the second ultrasonic split signal band.

9 is a conceptual diagram illustrating an operation of the mobile commerce service providing apparatus 120 according to an embodiment of the present invention.

In FIG. 9, a mobile commerce service operation in consideration of identification information of a user of the mobile commerce service providing apparatus 120 is started.

Referring to FIG. 9, the mobile commerce service providing apparatus 120 may provide a mobile commerce service for the user device 140 based on a virtual ID mapped with identification information of the user device 140. The mobile commerce service providing apparatus 120 may provide a mobile commerce service by grouping user devices according to membership levels.

For example, the mobile commerce service providing apparatus 120 may provide a mobile commerce service 1 915 to a member of a grade 1 910, and a mobile commerce service 2 925 to a member of a grade 2 920. In addition, the mobile commerce service 3 935 may be provided to members of the grade 3 930. As a specific example, the mobile commerce service 1 915 may be a discount rate 10% coupon providing service, the mobile commerce service 2 925 may be a discount rate 20% coupon providing service, and the mobile commerce service 3 935 may be a discount rate 30% coupon providing service.

The mobile commerce service providing apparatus 120 classifies at least one user device 140 corresponding to the first-class member into group 1 based on the identification information of the user, and at least one user device 140 corresponding to the second-class member. ) Can be classified into group 2, and at least one user device 140 corresponding to the third-class member can be classified into group 3.

After the classification, the mobile commerce service providing apparatus 120 provides the mobile commerce service 1 915 to the user device 140 included in the group 1, and the mobile commerce service 2 (the user commerce 140 included in the group 2). 925, and the mobile commerce service 3 935 to the user device 140 included in the group 3.

For the mobile commerce service according to the above grade, the data for the mobile commerce service may be masked by an identifier according to the membership grade. For example, data for mobile coverage service 1 915 may be masked by identifier 1 that only user device 140 included in group 1 can decode. Thus, data for mobile coverage service 1 915 can only be decoded by user device 140 included in group 1. In the same way, the data for mobile coverage service2 925 may be masked by an identifier2 that only user equipment 140 included in group2 can decode. Thus, data for mobile coverage service2 925 can be decoded only by user device 140 included in group2.

In addition, when the mobile commerce service providing apparatus 120 detects the identification information of the new user device 140 in the signal transmitted by the ultrasonic transmitter / ultrasound receiver 100, the mobile commerce service providing device 120 may consider the identification information of the user device 140. The user device 140 may be included in a specific group.

In addition, the mobile commerce service providing apparatus 120 may provide a mobile cover service by classifying a service for each grade and an unconcerned grade service. The grade-specific service is a service provided in consideration of the grade of the user device 140, and the grade unconcerned service is a service provided without considering the grade of the user device 140. The mobile commerce service providing apparatus 120 may transmit data for a mobile commerce service by masking with an identifier for each grade in consideration of the grade of the user device 140 as described above. The mobile commerce service providing apparatus 120 may not consider the rating of the user device as described above in the case of the unconcerned rating service, and may transmit data for the mobile commerce service without masking based on the class identifier.

According to the exemplary embodiment of the present invention, the mobile commerce service providing apparatus 120 may manage so that information on the mobile commerce service is not unnecessary and redundantly transmitted to the same user device 140.

The mobile commerce service providing apparatus 120 may periodically transmit information for a mobile commerce service. In this case, if the user is located in front of the POS, the sales desk is long, the user may continuously receive information for the mobile commerce service duplicated, and the fatigue of the user may be increased due to the continuous transmission of the same information. . Therefore, according to an embodiment of the present invention, when the mobile commerce service providing apparatus 120 is predicted that the information for the mobile commerce service is transmitted at least equal to the set number of times by predicting the number of times the user receives the information, the corresponding user device 140 ) May stop the transmission of information for the mobile commerce service.

The mobile commerce service providing apparatus 120 may calculate a time in which the user device 140 stays in a predetermined area. The location of the user device 140 may be tracked based on the ultrasonic transmitter / ultrasound receiver 100, and the mobile commerce service providing device 120 may calculate a time for which the user device stays in a predetermined area. The mobile commerce service providing apparatus 120 may determine the number of times the mobile commerce service information is transmitted to the user device in consideration of the time at which the user device stays in a certain area and a transmission cycle of information for mobile commerce service (hereinafter, referred to as mobile commerce service information). You can predict it. The prediction value of the number of times the mobile commerce service information is transmitted to the user device may be expressed in terms of the number of predictions of the mobile commerce service information transmission.

If the number of mobile commerce service information transmission predictions exceeds a preset maximum number of transmissions (for example, one to two times), the mobile commerce service information may not be transmitted to the user device 140. The mobile commerce service providing apparatus 120 may set the maximum number of information transmissions, and may limit the transmission of information for the mobile commerce service to the user device 140 according to the set maximum number of information transmissions.

As a specific example, the mobile commerce service providing apparatus 120 may manage information about a time in which each of the user devices 1 to 5 stays in a predetermined area (hereinafter, referred to as a mobile commerce service area) where the mobile commerce service can be received. It may be assumed that user device 1 stays in the mobile commerce service area for 5 minutes, user device 2 for 4 minutes, user device 3 for 3 minutes, user device 4 for 2 minutes, and user device 5 for 1 minute. If the transmission period of the mobile commerce service information is 2 minutes, the mobile commerce service providing apparatus 120 may predict the mobile commerce service information transmission of the user device 1 twice, and the mobile commerce service information transmission prediction number of the user device 2 may be Two times, the mobile commerce service information transmission prediction number of the user device 3 can be determined once, the mobile commerce service information transmission prediction number of the user device 4 is determined once, and the mobile commerce service information transmission prediction number of the user device 5 can be determined as 0 times. .

If the maximum number of times of transmitting information is set, the mobile commerce service providing apparatus 120 may transmit the mobile commerce service information only to the user device 3, the user device 4, and the user device 5 except the user device 1 and the user device 2. .

Instead of predicting the number of times of information transmission for the mobile commerce service, the number of times of information transmission for the mobile commerce service may be actually stored and managed in a database. That is, the database may store the number of times of transmitting information for the mobile commerce service for each user device, and the mobile commerce service providing apparatus 120 considers the number of times of transmitting information for the mobile commerce service for each user device stored in the database. It may be determined whether to transmit information for the mobile commerce service to the device.

As a specific example, the database of the mobile commerce service providing apparatus 120 stores the actual number of transmissions so that the mobile commerce service information number of the user device 1 is twice, the mobile commerce service information transmission number of the user device 2 is twice, and the user device 3 The number of times of transmitting mobile commerce service information of the user may be stored once, the number of times of transmitting mobile commerce service information of the user device 4 may be stored, and the number of times of transmitting mobile commerce service information of the user device 5 may be zero. If the maximum number of times of transmitting information is set, the mobile commerce service providing apparatus 120 may transmit the mobile commerce service information only to the user device 3, the user device 4, and the user device 5 except the user device 1 and the user device 2. .

According to another embodiment of the present invention, the information about the number of times of receiving the mobile commerce service information may be transmitted by the user device 140 to the mobile commerce service providing apparatus 120. For example, when the user device 140 receives the mobile commerce service information from the mobile commerce service providing apparatus 120, the user device 140 may transmit an acknowledgment signal in response to the mobile commerce service information. The ACK signal transmitted by the user device 140 may include information on the number of times of receiving the corresponding mobile commerce service information. For example, when the maximum information transmission count is set to three times, the ACK signal may include a 2-bit mobile commerce service information reception count field. When the value of the service information receiving field is '00', the service information receiving number field means receiving the mobile commerce service information once, and when the value of the service information receiving field is '01', the service information receiving number Field means 2 times reception of mobile commerce service information. When the value of the service information reception frequency field is '10', it means 3 times reception of mobile commerce service information, and the value of the service information reception frequency field is '11'. ', May mean four receptions of mobile commerce service information. The mobile commerce service providing apparatus 120 may additionally determine whether to provide mobile commerce service information based on the ACK signal.

Alternatively, the user device 140 may directly set the maximum number of receptions of the mobile commerce service information, and do not additionally transmit the corresponding mobile commerce service information through the ACK signal transmitted by the user device 140 according to the set maximum number of receptions. Information to request to speak may be transmitted. When the user device 140 receives the mobile commerce service information from the mobile commerce service providing apparatus 120, the user device 140 may transmit an ACK signal in response to the mobile commerce service information. The ACK signal transmitted by the user device 140 may additionally include bit information indicating not to transmit the mobile commerce service information. For example, when the value of the bit indicating not to transmit the mobile commerce service information is 1, the mobile commerce service providing apparatus 120 may not additionally transmit the mobile commerce service information. On the contrary, when the value of the bit indicating not to transmit the mobile commerce service information is 0, the mobile commerce service providing apparatus 120 may additionally transmit the mobile commerce service information.

In addition, according to an embodiment of the present invention, the mobile commerce service providing apparatus 120 may determine the transmission cycle of mobile commerce service information based on the number of user devices 140 located in the mobile commerce service area. That is, when there are relatively many user devices 140 located in the mobile commerce service area, the waiting time is increased in the mobile commerce service area, and thus, the time for providing the mobile commerce service is also relatively long. Accordingly, the mobile commerce service providing apparatus 120 may provide the mobile commerce service to the user device 140 even when the transmission period of the mobile commerce service information is relatively set. On the other hand, when there are relatively few user devices located in the mobile commerce service area, since the waiting time is shortened in the mobile commerce service area, the time for providing the mobile commerce service is also shortened relatively. Accordingly, the mobile commerce service providing apparatus 120 may provide a mobile commerce service to the user device 140 by setting a relatively short transmission period of the mobile commerce service information.

The mobile commerce service providing apparatus 120 may obtain information about the number of user devices 140 located in the mobile commerce service area based on the location information of the user device 140 received from the ultrasonic transmitter / ultrasound receiver 100. Can be. The mobile commerce service providing apparatus 120 may classify the number of the user devices 140 into a predetermined section and determine a transmission period of the mobile commerce service information according to the classified section. The transmission period of the mobile commerce service information according to the number of user devices may be predefined in a table or may be set according to the setting of the mobile commerce service provider. For example, if the number of user devices located in the mobile commerce service area is less than 10, the transmission period of mobile commerce service information is set to 1 minute, and the number of user devices 140 located in the mobile commerce service area is 10. When the number is less than 20, the transmission period of the mobile commerce service information is set to 2 minutes, and when the number of the user devices 140 located in the mobile commerce service area is 20 or more and less than 30, the transmission period of the mobile commerce service information is It can be set to 3 minutes. The unnecessary transmission of unnecessary mobile commerce service information may be limited based on the setting of the transmission period of the adaptive mobile commerce service information.
